My method of mimicing the style would be by drawing whatever I want in real life (With a vauge sort of World of Goo), then adding details in photoshop. If you don't have photoshop, use https://pixlr.com/editor/ . It may not be good as Photoshop, but it's free (and online).

Does that help?

I give critique to recent levels.
